Apply Firewall Policy to Bond0 vif

I have a brand new EdgeRouter Pro running the latest firmware (first thing I did). I created an 802.3ad bond interface Bond0 and then I created a couple vifs for various VLANs on bond0 and then I created a firewall policy. When I try to apply the firewall policy to the bond0.98 interface the GUI hangs. It just sits there spinning. In the CLI I tried this command: set interfaces bonding bond0 vif 97 firewall in TEST_IN

But it says the specified configuration node is not valid...what am I missing? Can I not do this?
